How do you simplify (5 + 2i ) - ( 2 + 3i )? Precalculus Complex Numbers in Trigonometric Form Complex Number Plane 1 Answer Rachel Feb 25, 2016 3-i Explanation: If we begin with (5+2i)-(2+3i), the first step is to multiply the -1 into the 2+3i parentheses, which becomes 5+2i-2-3i. From here we just combine like-terms, like 5 and -2, as well as 2i and -3i. This leaves us with 3-i. Answer link Related questions What is the complex number plane?
